Rail System with Riding Board

ABSTRACT

The invention relates to a cost-effective rail system which can be driven upon by a board. Since the rail system can be easily assembled and disassembled again, the path can be very easily varied. The rail system is disposed in a sloping manner for this purpose. This can be done by constructing the rail system on a mountain slope, for example. By way of a specially designed board for this purpose, a so-called riding board on which a person can stand, the person can then ride down the slope. The riding board comprises a braking system.

The invention relates to a rail system according to the preamble ofpatent claim 1 as well as to a riding board according to the preamble ofpatent claim 10.

Especially the summer time when there is no snow on the ground or areaswith low snowfall offer the opportunity to provide devices with which itis feasible to travel down a mountain slope without having to depend onsnow.

Known is a leisure apparatus that comprises a board with which it ispossible to travel down a track surface (US 2006/0214385 A1). The lengthof the track surface can herein be variable.

Known is further an illuminated track for snowboards, which track iscomprised of a rail whose surface is transparent and on whichsnowboards, skateboards or the like equipment can travel (US2006/0174428 A1). This track is disposed on supports such that the trackruns above the ground.

Known is furthermore a vehicle for a rail system of a roller coastercomprising means of traveling which connect the vehicle with the railsystem and which can absorb horizontal as well as also vertical forces(DE 10 2005 038 360 B3). This vehicle comprises moreover a board whichhas at least a standing surface as well as means for the spring- andshock-absorbed bearing of the board on the traveling means.

Lastly, a rail system is known which is also disposed on supports (JP2004 057733). The rails in this system are connected with one anotherusing connection elements.

The present invention addresses the problem of providing a rail systemon which at least one board can travel.

The problem is resolved according to the features of claims 1 and 10.

The invention thus relates to a cost-effective rail system on which aboard can travel. Since the rail system can be readily assembled anddisassembled again, the track can be varied quite easily. The railsystem for this purpose is disposed on a slope. This can be carried out,for example, thereby that the rail system is developed on a mountainslope. By means of a board, a so-called riding board specificallyfabricated for this purpose, on which a person can stand, this personcan subsequently travel down the slope. The riding board hereincomprises a braking system.

It is, however, also feasible to provide a riding board with two boardsconnected via rails with one another, on which a person can stand. Bothboards are so connected with one another that they form a brakingsystem. For this purpose the boards on the rails connecting them must bemoved away from each other.

Each of these two variants of the riding boards comprises on itsunderside several wheels which can be disposed on the rail system. Auser thus glides not on the rail system but rather rolls down the slopeon this rail system. The user can regulate the downward travel speedthereby that the riding boards comprise a braking system.

In the following the rail system as well as the two variants of theriding boards are depicted in the Figures and in the following areexplained in further detail. In the drawing depict:

FIG. 13 a cross section G-G through the riding board depicted in FIG. 12b with the braking system,

FIG. 14 a and FIG. 14 b a variant of the riding board depicted in FIGS.12 a and 12 b with a braking system.

FIG. 1 depicts a rail system comprising several rail line sections 2 to8. These rail line sections 2 to 8 can be implemented in the form ofcurves or also straight. However, in FIG. 1 only curved rail linesections 2 to 8 are depicted. This rail system 1 is preferably comprisedof flexible material, preferably Al. These rail line sections 2 to 8 aredisposed sequentially one after the other and each is securely anchoredin the ground. The rail system 1 is therewith not disposed on supportsabove the ground but rather directly on the ground. However, it is alsofeasible disposing the rail system 1 on supports.

Evident are also several persons 9 to 11 each traveling down a slope ona riding board 12 to 14 in the direction of arrow 15. Person 11 standsherein on only one board 20 while persons 9, 10 are standing with onefoot each on a board 16, 17 and 18, 19. The two boards 16, 17 as well as18, 19 are connected using rails, not visible in FIG. 1.

The person herein holds in one hand a rope 237 connected with the board17 of the riding board 12. Should person 9 jump or fall off the ridingboard 12, this person 9 can quickly remove the riding board 12 from therail system 1. Therewith is prevented that the riding board 12 travelswithout the person 9 in the direction of arrow 15, e.g. down the slope,and in this way hinders or even endangers the persons following.

As is evident in FIG. 1, person 10 also holds such a rope 238 in onehand. This rope 238 is also connected with the front board 19 of ridingboard 13. It is understood that the riding boards 12, 13 can also beequipped without such ropes 237, 238.

Evident is also that the person 11 standing on the riding board 14 holdsa traction device 21, for example a rope, which is connected with theriding board 14. By means of the traction device 21 the braking systemof the riding board 14 can be controlled. However, the braking system isnot evident in FIG. 1.

FIG. 2 shows the rail system 1 according to FIG. 1 in a side view,wherein in FIG. 2 only a cut-out of the rail system depicted in FIG. 1is shown. Evident are the sequentially disposed rail line sections 7, 8,which are comprised of top parts 233, 234 disposed on several base parts229 to 232. This rail system 1 is disposed on a substrate 51. The lengthof a top part 233, 234 corresponds to the length of a line section 7, 8.Each top part 233, 234 is disposed on several base parts 229, 230 and230, 231, 232, respectively. These top parts 233, 234 are connected withthe base parts 229 to 232 via connection means not evident in FIG. 2.The base parts include, furthermore, windows, which however are notshown in FIG. 2 for the sake of clarity.

It is, however, evident that the top parts 233, 234 jointly are at leastpartially disposed on the base part 230. The top parts 233, 234 areconsequently disposed offset with respect to the base parts. Throughthis disposition a stable rail system 1 is obtained which can withstandhigh pressures generated when traveling on the rail system 1.

As can be seen in FIG. 2, the base parts 229 to 232 are disposedsequentially, the base parts 229 to 232 being in contact with oneanother. However, it is understood that the base parts 229 to 232 canalso have a certain spacing from one another.

Evident are also two middle parts 235, 236 which form a portion of thetop parts 233, 234. Since they are disposed in the top parts 233, 234,these middle parts 235, 236 are indicated by dashed lines. These middleparts 235, 236 are also offset, which contributes significantly to thestability of the rail system 1.

FIG. 3 shows a cut-out of the rail system 1 depicted in FIG. 1 accordingto cross section A-A. The rail system 1 includes a top part 22 comprisedof a middle part 23 as well as two side parts 24, 25 disposed thereon.This top part 22 is disposed on a base part 26 and secured thereon withsecurement means, for example bolts. In FIG. 3 two openings 27, 28 canbe seen, which are disposed on a top side 29 of the middle part 23 andthrough which the bolts, not shown in FIG. 3, can be guided. The middlepart 23 has a wall 30 which encompasses a hollow volume 31.

When assembling the rail system 1, first, the middle part 23 isconnected by means of connection elements with the base part 26.Subsequently the side parts 24, 25 are disposed on the middle part 23and the connection elements are tightened whereby the side parts 24, 25are fixed on the middle part 23. The connection elements are, however,not shown in FIG. 3. The top part 22 is therewith securely seated on thebase part. Any slipping of the top part 22 is consequently not possible.

The wall 30 includes further four sections 32 to 35 realized as hooks.Herein two sections 32, 33 and 34, 35 each are disposed on each side ofthe middle part 23. Each of these sections 32 to 35 encompasses at leastpartially an L-shaped section 36 to 39 of the side parts 24, 25. Sidepart 24 is mirror symmetric with respect to side part 25 and hassubstantially the shape of an “E”.

Through this disposition of side parts 24, 25 and middle part 23 the toppart 22 is, in principle, a resilient element which withstands highpressures.

Side parts 24, 25 are each disposed with their L-shaped section 36, 39on the base part 26. The L-shaped sections 36, 39 are connected with asection forming the sidewall 40, 41 of the side parts 24, 25. Thesidewall 40 and 41 of the side part 24 and 25, respectively, extendsobliquely upwardly, wherein the internal angle β between the L-shapedsection 36 and the sidewall 40, and the L-shaped section 39 and thesidewall 41, respectively, is less than 90°. This angle β is hereinpreferably 60° to 80° and especially preferred is 75°.

The L-shaped sections 38 and 37 are disposed in the central region ofthe particular sidewall 40 and 41, respectively. The L-shaped section 37is herein disposed above the section 36 and the L-shaped section 38above section 39. The angle β is here also preferably 60° to 80° andespecially preferred is 75°. The upper region 42 and 43 of the sideparts 24 and 25, respectively, is realized substantially U-shaped andlaterally forms closure with the upper side 29 of middle part 23.

The base part 26, which is substantially structured in the shape of abox, includes a floor 44 which is connected across two sidewalls 45, 46with a ceiling. On this ceiling 47 rest the two side parts 24, 25 of toppart 22. The middle part 23 is not in contact with ceiling 47 since itis suspended between the two side parts 24, 25 of top part 22. It isherein obvious to a person of skill in the art that the base part 26also suffices without floor. The base part 26 can thereby be pressed atleast partially into the substrate 51. The base part 26 is therebysecurely disposed in the substrate 51.

The sidewalls 45, 46 of base part 26 additionally include windowsthrough which a securement means can be guided from the outside. Thesewindows are located obliquely opposite to one another. In FIG. 3 onlythe windows 48, 49 can be seen. Evident is also that the floor 44 of thebase part 26 has an opening 50 in the proximity of the windows 48.Through this opening 50 is slid a securement means, not shown in FIG. 3,guided through the window 48. This securement means effects that thebase part 26 is securely connected with the substrate 51 on which it isdisposed. Slipping is consequently not possible.

In the proximity of window 48 the wall is structured in the shape of aroof, wherein in FIG. 3 a peak 56 of this roof-shaped structure can beseen. The wall 52 descends here obliquely in the direction of opening50. Between the wall 52 and the floor 44 can further be seen aperpendicular wall 53 which connects the floor 44 with the wall 52.Opposite the wall 52 is evident a further wall 54 which connects thefloor 44 with the ceiling 47 of the box-shaped base part 26. Between thewall 52 and the wall 54, consequently, is formed an interspace whichserves as a guide-through 55 for the securement means.

FIG. 4 shows a top view onto the base part 26 according to FIG. 3without the top part 22. The flat ceiling 47 of the base part 26includes several openings 57 to 59, on the sides of which windows 48,49, 60 are disposed through each of which a securement means can beguided. For the sake of clarity a securement means is not shown. Evidentare in openings 57 to 59 peaks 56, 61, 62 of a roof-shaped structure.The windows 48, 60 depicted in FIG. 4 are herein disposed obliquelyopposite to window 49. Between the windows 48, 49, 60 are disposedopenings 27, 28, 65, each in the center of ceiling 47, into whichopenings connection elements can be introduced. By means of theseconnection elements, which are not depicted in FIG. 4, the base part 26can be secured with the middle part 23 of the top part 22, not shownhere, such that the top part 22 cannot slip off the base part 26.

Next to opening 27 are disposed two relatively large openings 66, 67,through which also connection elements can be guided. By means of theseconnection elements the base part 26 is secured with the substrate onwhich it is disposed. Such connection elements are, however, notdepicted in FIG. 4.

FIG. 5 shows a cross section B-B through the base part 26 depicted inFIG. 4. The base part 26 has in this section 81 a roof-shaped region 69which includes the wall 52. This wall 52 is disposed parallel to wall 54and spaced apart from it at such distance that a guide-through 55 for asecurement element is provided.

FIG. 6 shows a line section 70 of the base part 26 depicted in FIG. 4according to cross section C-C. The opening 58 in ceiling 47 is hereindisposed above a guide-through 71 for a securement element not shown inFIG. 6. This guide-through 71 is located between two walls 72, 73.Evident is also the peak 61 of a roof-shaped section 74 which bears thewall 72.

In FIG. 7 is evident the line section 70 of the base part 26 in which asecurement element 75, for example a tent peg, is guided through theguide-through 71. As can be seen in FIG. 7, the securement element 75rests with the curved end 76 on a wall 77 of section 74. The securementelement 75 is only disposed with its upper region 78 in the base part26, wherein it rests on the roof-shaped section 74. The lower end 79 ofsecurement element 75 is disposed in the substrate 51. It is herein ofadvantage for the securement element 75 to be as long as possible inorder to be able to anchor it securely in the substrate 51.

The roof-shaped section 74 serves consequently as a holding element orsupport surface for the securement element 75 guided through theguide-through 71. It is understood that, depending on the form of thesecurement element, the section 74 can also be structured differently.

FIG. 8 shows a section 80 of the base part 26 depicted in FIG. 4 alongcross section D-D. Evident is again the box-shaped base part 26 with theflat ceiling 47 and the two sidewalls 45, 46, which connect the ceiling47 with the floor 44. In the central region of ceiling 47 can be seen anopening 28 for the through-guidance of a connection element, wherein theconnection element is not depicted. Beneath opening 28 can be seen acavity 82 which is encompassed by walls 83, 84. Since this cavity 82does not include a bottom, the cavity 82 is open toward the substrate51. Two hollow volumes 85, 86 located on both sides of cavity 82 canalso be seen.

FIG. 9 shows a section 87 of the base part 26 depicted in FIG. 4.Evident is again an opening 27 for the through-guidance of a connectionelement, not depicted in FIG. 9, by means of which the base part 26 canbe connected with the top part 22, not shown here.

Beneath opening 27 is located a cavity 88, disposed directly above thesubstrate 51 and laterally encompassed by two walls 89, 90. These walls89, 90 are each located opposite a wall 91, 92 and, together with thefloor 44 and the ceiling 47, form each a hollow volume 68 and 93,respectively. Next to these hollow volumes 68, 93 bordering on walls 91and 92, respectively, one cavity 94, 95 each is located. These cavities94, 95 are also directly in contact with the substrate 51. Above each ofthe cavities 94, 95 is an opening 66, 67. Through these openings 66, 67securement means, for example spikes, can be guided. These securementmeans, not depicted here, serve for connecting the base part 26 with thesubstrate 51. For this purpose the securement means are guided fromabove through the openings 66, 67 and introduced into the substrate 51.It can consequently be clearly seen that the walls 45, 46, 54, 83, 84,52, 72, 73, 89 to 92 of sections 70, 80, 81 and 87 form between thefloor 44 and the ceiling 47 of base part 26, in principle, strut memberswith cavities and hollow volumes disposed therein, which contributeespecially to the stability of the rail system 1, since these withstandhigh pressures. The material of which the rail system 1 is comprised canherein be a metal, a metal alloy and/or a synthetic material. However,the rail system is preferably comprised of Al.

FIG. 10 shows a rail system 96 which represents a variant of the railsystem 1 of FIG. 3. On the rail system 96 is disposed a riding board 97.The rail system 96 differs from the rail system 1 only by the structureof the base part. The rail system 96 includes, for example, a base part98 which does not have a floor wherewith the walls 99 to 102 aredisposed between the substrate 51 and a ceiling 103 of the base part 98.

However, it is understood that the base part 98 can also have a floor,with which in this case the base part 98 is in contact with thesubstrate 51.

Seen can be further two securement elements 113, 114, which, with anupper region 225, 226, are at least partially disposed in base part 98and with a lower region 227, 228 are disposed in the substrate 51. Sincethe upper regions 225, 226 of securement elements 113, 114 are disposedbehind a connection element 104, these are shown only schematically. Thesecurement elements 113, 114 are disposed with their lower region 227,228 deeply in the substrate 51, whereby the rail system 98 is securelyanchored in the substrate 51.

The top part 22 corresponds to the top part depicted in FIG. 3 andcomprises a middle part 23 encompassed by two side parts 24, 25. Throughthis middle part 23 the connection element 104, for example a bolt, isguided which, with one end 105 is guided through the opening 106disposed in the middle part 23 for a connection element. The end ofconnection element 104 is secured with a sealing 107, for example ofrubber, resting in contact on opening 106. The other end 108 of theconnection element 104 extends through an opening 109, disposed on thelower section of middle part 23, through an opening 110 in the ceiling103 of base part 98 into a cavity 111. The connection element 104 ishere provided with a fitting nut 112. The connection element 104 can betightened by means of this nut 112.

The connection element 104 is preferably a bolt with a threadingdisposed in the middle part 23. It is herein feasible for acounterthreading to be disposed in the middle part 23 in which the boltis supported. However, FIG. 10 does not depict a counterthreading.Since, as evident in FIG. 10, the middle part 23 is suspended in theside parts 24, 25, the middle part 23 is moved in the direction of theceiling 103 of base part 98 by tightening the connection element 104.

The riding board 97 disposed on the rail system 96 has a frame 115,which is provided with several pairs of wheels. Since in FIG. 10 a crosssection through the riding board 97 is depicted, only the wheel pairs116 to 118 are visible in FIG. 10. The wheel pair 116 is herein disposedon the sidewall 40 and the wheel pair 118 on the sidewall 41 of sideparts 24, 25. Wheel pair 117 is located on the upper region 42, 43 ofsidewalls 40 and 41 of side parts 24, 25, respectively.

The frame 115 is comprised of two opposing, substantially U-shapedsections 119, 120, which are connected with one another via one of theirtwo limbs 121, 122. The connection of these two limbs 121, 122 forms asection 123, which forms the top side of the riding board 97. On thissection 123 is disposed a board 124 on which a person, not depictedhere, can stand. This involves, consequently, a variant of a ridingboard on which a person can stand with both feet.

In the central region of section 123 is located the wheel pair 117,which comprises two wheels 126, 127 disposed rotatably on a shaft 125.The shaft 125 rests in a bearing 128, wherein the shaft 125 includes onboth sides fixing elements 129, 130 which ensure that the shaft 125 doesnot become detached from the bearing 128. It can be seen that the wheelpair 117 is located in the frame 115 in front of the two wheel pairs116, 118, e.g. is disposed offset with respect to them. As the wheelpair 118, the wheel pair 116 is also disposed in two parallel extendingelements 131, 132 and 133, 134, respectively, wherein the elements 131,134 form each one limb 131, 134 of the U-shaped section 120 and 119,respectively, of frame 115. The element 133 and 132 is herein connectedvia a strut member 135 and 136, respectively, with the section 123 offrame 115.

The wheel pairs 116, 118 have each two wheels 139, 140 and 141, 142,respectively, disposed movably on a shaft 137 and 138, respectively. Itis understood that the wheel pairs 116, 118 can be disposed on ballbearings. Shafts 137, 138 are herein bearing supported in elements 131,132 and 133, 134, respectively. As is the case in wheel pair 117, wheelpairs 116, 118 also include shafts 137, 138, which are provided at theirends with fixing elements 143 to 146. These fixing elements 143 to 146prevent the shafts 137, 138 from becoming detached from the elements 131to 134.

Wheels 126, 127, 139, 140, 141, 142 of these wheel pairs 116 to 118 canherein also be ball bearings. These ball bearings can additionally berubberized.

Although in FIG. 10 the riding board 97 has wheel pairs with two wheelseach, it is obvious that, instead of a wheel pair, also only one wheelcan be provided. It is, further, also conceivable to array three or morewheels instead of a wheel pair. It is herein feasible to provide ariding board which includes only the lateral wheel pairs or wheels,alternatively, which are disposed at an inner angle α of 10° to 30°,preferably at an angle α of 15°, with respect to the board.

FIG. 11 shows a view of the riding board 97 according to FIG. 10 frombelow, e.g. seen in the direction of arrow F. Seen can be the wheelpairs 116 to 118 disposed on frame 115. Opposite to these wheel pairs116 to 118 are disposed further wheel pairs 147 to 149. All wheel pairs116 to 118, 147 to 149 are supported rotatably via shafts. However, inFIG. 11 only the shafts 125, 151 disposed on bearings 128, 150 can beseen. As was the case with the wheel pairs 116 to 118, the wheel pairs147 to 149 also have fixing elements. However, in FIG. 11 only thefixing elements 129, 130, 144, 146, 152 to 155 can be seen.

FIGS. 12 a and 12 b show schematically a braking system 63 of the ridingboard 97 with the wheel pairs 147 to 149, 116 to 118. The braking system63 comprises one rod-shaped element 156, 157 on each side of the ridingboard 97. These rod-shaped elements 156, 157 are disposed via a springelement 158, 159 each on the rearward section 160 of the riding board97. Thus the travel direction of the riding board 97 is indicated by thearrow 161.

On both elements 156, 157 are disposed means 162, 163, by means of whichbraking blocks 164, 165 can be moved in the direction of arrows 166,167. Between these braking blocks 164, 165 is disposed the top part 22which in FIGS. 12 a and 12 b is only depicted segment-wise andschematically for the sake of clarity.

Evident are two end blocks 168, 169 which are located opposite oneanother. On the elements 156, 157, moreover, one band 170, 171 each isdisposed. These bands 170, 171 are guided through openings 172, 173 fromthe underside of the riding board 97 such that a person standing on theriding board 97 can grasp these. For this purpose the two bands 170, 171are joined to form a traction device 174, for example a rope 174. Thistraction device 174 can be held by a person, not depicted in FIGS. 12 aand 12 b.

However, such a person 11 is depicted in FIG. 1. By pulling the tractiondevice 174 the elements 156 and 157 with the means 162, 163 disposedthereon are moved in the direction of arrow 175 or 176. Thereby that thebands 170, 171 are combined to form this traction device 174, themovement of the elements 156, 157 with the means 162, 163, disposedthereon, takes place synchronously.

By pulling the traction device 174, the position depicted in FIG. 12 bis obtained. Evident is in FIG. 12 b that the spring elements 158, 159are tensioned and the elements 156, 157 have been moved in the directionof arrows 175, 176. The means 162, 163 disposed on elements 156, 157have also been moved in the direction of arrows 175, 176 andspecifically up to the end blocks 168, 169 which serve as stops.

The braking blocks 164, 165 comprised substantially of flexible materialhave herein been moved with their broader regions in the direction ofarrows 166, 167, e.g. in the direction of top part 22 of the railsystem. Therewith the braking blocks 164, 165 come into contact with thetop part 22 which launches a braking process.

When the traction device 174 is released again, the elements 156, 157are retracted through the spring elements 158, 159 in the direction ofarrows 177, 178. The spring elements 158, 159 thereby arrive again inthe position depicted in FIG. 12 a, e.g. in their resting position.Thereby that the means 162, 163 are also carried back again into thestarting position depicted in FIG. 12 a, the contact between the toppart 22 and the braking blocks 164, 165 is again released, since thebroader regions of the braking blocks 164, 165 are again moved in thedirection of arrows 179, 180, in order to reach the starting positiondepicted in FIG. 12 a.

As can be seen in FIGS. 12 a and 12 b, the braking blocks 156, 157 aredisposed in the rearward section 160 on retention elements 181 to 184.It becomes thereby possible that only the front broader region of thebraking blocks 164, 165 is moved in the direction of the top part 22.

FIG. 13 shows a cross section G-G through the riding board 97 depictedin FIG. 12 b with the braking system 63. The wheel pair 117 is not shownfor the sake of clarity. Evident are the elements 156, 157 with themeans 163, 162 disposed thereon. The elements 156, 157 are hereindisposed between the sections 185 to 188. These sections 185 to 188 forma portion of the frame 115 and serve as guide elements for therod-shaped elements 156, 157. The means 163, 162 thereby come to be incontact with the braking blocks 164, 165 and press these in thedirection of arrows 166, 167. Thereby the braking blocks 164, 165 comeinto contact with the sidewalls 40 and 41 of side parts 24 and 25,respectively, of top part 22, wherewith in FIG. 13 the braking processis also shown.

In FIGS. 14 a and 14 b is depicted a riding board 64 comprised of twoframes 191, 192 connected with one another via rails 189, 190. On eachof these frames 191, 192 a board is disposed which, however, is notdepicted in FIGS. 14 a and 14 b. Therewith in FIGS. 14 a and 14 b avariant of the riding board 97 according to FIGS. 12 a and 12 b isshown, on which a person must stand with one leg each on a boarddisposed on the frames 191 or 192.

The riding board 64 also comprises several wheel pairs 193 to 204,wherein each of the frames 191, 192 is provided with six wheel pairseach. The disposition of these wheel pairs 193 to 204 corresponds tothat of the riding board 97. Each of the frames 191, 192 includes abraking system 213, 214, each of which comprises two braking blocks 205,206 and 207, 208, respectively, as well as two end blocks 209, 210 and211, 212, respectively. These braking blocks 205 to 208 are preferablycomprised of rubber or another flexible material. Thus far the brakingsystem 213, 214 is similar to the braking system 63 of riding board 97.However, the rails 189, 190 assume the function of elements 156, 157 ofthe braking system 63. At both ends of rails 189 and 190 means 215, 217and 216, 218, respectively, are disposed with which the braking blocks205 to 208 can be moved in the direction of arrows 219, 220, e.g. in thedirection of the top part 22 depicted in FIGS. 14 a and 14 b.Consequently, the braking blocks 205 to 208 are brought into contactwith the top part 22 whereby the braking process is initiated. However,in the case of riding board 64 the braking process is not initiatedthrough actuation of a traction device although such would also befeasible.

As can be seen in FIG. 14 a, the two frames 191, 192 are disposedadjacent to one another wherein they are nearly in contact with oneanother. If the two frames 191, 192 are now moved in the direction ofarrow 221 and 222, respectively, they are moved away from one anotheralong the rails 189, 190.

Unlike in the braking system 63 of riding board 97, herein the means161, 162 of the elements 156, 157 are not moved but rather are theframes 191, 192 with the braking blocks 205 to 208. The braking processproper, however, does not differ, since in FIG. 14 b the means 215 to218 also move the broader regions of braking blocks 205 to 208 in thedirection of arrows 219, 220, e.g. in the direction of the top part 22.Therewith in the braking system 213, 214 the braking blocks 205 to 208are also brought into contact with the top part 22. Through the rails189, 190, which connect the two frames 191, 192 with one another, thetwo braking systems 213, 214, however form a unit since the brakingblocks 205 to 208 are also addressed synchronously via the means 215 to218 disposed on the rails 189, 190 and are therewith moved.

If the braking process is to be terminated, the frames 191, 192 with theboards disposed thereon must be moved in the direction of arrows 223 and224, respectively, e.g. toward one another. This takes place therebythat the person moves his legs again in the direction of arrows 223,224. Therewith is obvious that through a relative movement of the means162, 163, 215 to 218 with respect to the braking blocks 164, 165, 205 to208 the braking process can be controlled.

These braking blocks 164, 165, 205 to 208 are comprised of asubstantially flexible material, such as for example rubber. Further,these braking blocks are readily attachable on the riding board and arereadily detachable again from the riding board. If such a braking blockis consequently worn down, it can be removed readily from the ridingboard and be replaced by a new one.
